Never happen. McCaskey (Bears president Mike, grandson of George Halas) would sooner grab the starter from Slippery Rock than to grab an experienced NFL QB. He's too damned cheap to do otherwise. He gets experienced QB's....when their just about finished in the league, like Chris Chandler.
I thought getting Chandler was a really good move last yr. Little did I know that he could get hurt on a quarterback sneak. I have never seen that happen before.
